1. A secure and reliable digital wallet should be designed from at least five dimensions:
1. Security risk of running environment
the core file of encrypted digital currency Wallet - private key / mnemonics is stored on the terminal device, whether it is PC or mobile terminal, if the terminal device appears unsafe phenomenon, There is a very high security risk for the private key / mnemonic
at the beginning of design, a secure digital wallet can avoid the possibility of private key / mnemonics being stolen e to the running environment. The security problems of the running environment on the terminal mainly include virus software, operating system vulnerabilities and hardware vulnerabilities
2. The security risk of network transmission
the security of network transmission is more reflected in the ability to resist man in the middle attack. Man in the middle attack means that the attacker creates independent contact with both ends of the communication and exchanges the data they receive, so that both ends of the communication think that they are talking directly with each other through a private connection, but in fact the whole conversation is completely controlled by the attacker
although most digital wallet applications use the HTTPS protocol to communicate with the server, the man in the middle attack method is to get the content of the HTTPS protocol by installing a digital certificate in the user terminal
a secure digital wallet needs to be able to scan the legality of all the digital certificates in the terminal, check the proxy settings in the network transmission process, and ensure the security of the basic network communication environment
in the development of digital wallet, whether to use two-way verification for communication verification at the network transmission level is also an important criterion to measure the security of a digital wallet application
3. The security risk of file storage mode
for the private key / mnemonics of digital wallet, the storage mode of terminal device also needs to be paid attention to in the security design. The access right of private key / mnemonic file directory, the form of private key / mnemonic file storage and the design of encryption algorithm all need to be strictly designed
when we analyze the security of several mainstream digital wallets, we find that even the well-known digital wallets are random in the storage of private key / mnemonic words. There are both plaintext storage and encrypted storage, but the decryption key is fixed in the code, which can not play any role in security defense
4. The security risk of the application itself
the security risk of the application itself mainly focuses on the security defense of the application installation package itself
whether the application installation package has the ability of anti tampering is a very core technical ability. In addition, memory security, anti debugging ability, life cycle management of private key / mnemonics, security of debugging log and security of development process also need to be enhanced
5. Security risk of data backup
if the mobile application can be backed up, it can use the machine with more powerful computing performance to brutally crack the private key / mnemonics. For example, if android:allowBackup Property is set to allow backup, then the backup mechanism of the system can be used to back up the application data files, and the private key / mnemonics of the encrypted digital currency will be backed up to the external media, which breaks the security boundary design of the operating system from another direction
for the majority of users, the security of digital wallet also means the security of wealth, so we must be careful when choosing digital wallet
I have used several wallets such as coin letter socoin and coinplus
in terms of personal experience, socoin and coinplus are very simple and easy to use. They are not only decentralized multi-functional cross chain digital currency wallets with social functions, but also integrate Multi Chain multi currency wallets, payment and settlement platform, currency trading platform, social groups, information market and other functions, which can meet almost all your needs for digital currency in one stop.

LTC is the abbreviation of lightcoin. Lightcoin is inspired by bitcoin (BTC) and has the same implementation principle in technology. The creation and transfer of lightcoin is based on an open source encryption protocol and is not managed by any central authority
for the market of Leyte LTC, you can find it in the UK for financial information
3. 1： EP modification
EP in the game can be used by buying some props, but I don't think it's very easy to use, but there are some achievements that can be achieved by using EP
1. First of all, you need to have an ifile or something like that
2. Open ifile to find var / mobile / applications / devils at the gate / lbrary / preferences / com.imohoo.balu.plist; The devils at the gate is the game directory, and the names of each machine are different. You need to be patient with online games to find out the directory of waytd.app in the game directory, which is this
3. Click com.imohoo.balu.plist, and the options will appear
select "property sheet Editor" to find the number with EP, which is your current EP value. Don't worry about changing it, But it's better to be within 10000, 9900 I think is enough
now go back to the game, EP has become 9900, don't worry about buying props
2: money modification
in the game, the initial money given is only 200, and it grows very slowly afterwards. Obviously, the military expenditure of the Eighth Route Army is not as good as that of the aggressors.
teach you an easy way to modify money.
in the first step, you select the level you want to challenge, enter it, click pause, and then exit the game.
the last steps are the same as above, But you don't need to change the EP value (decide whether you want to change it or not)
change the place with red box in the picture
change the place with red box in the picture to about 6000, which is enough.
with money, you will be very happy.
with money, the first wave of enemies will be hit hard by you. OK, attacking the Japanese aggressors is not short of money

4. It's sad that I didn't even know when I committed a crime. Voluntariness is the most unreliable evidence to overturn a case.
5. I wrote a lot of blockchain project analysis before and after, from the initial bitcoin, Ethereum and EOS to various application-oriented projects, such as exchange, currency, u like and other content-based projects, including the project party's draft. I have formed a set pattern for project analysis in my mind. I know this framework after reading my project analysis articles. I analyze the project white paper according to "project introction, launch background, project innovation, project team, development trends, token and market, project risk, competitive proct analysis, suggestions and summary", or match the content and framework in the white paper, Some will be filled in, others will not be written out; Next is the supplementary information as evidence, combing ideas, and then according to their own understanding to write project analysis, so as to be regarded as their own project analysis. For project analysis, I can summarize three steps: the first step is to collect information (see white papers, search engines, official articles, etc.); The second step is to set the frame template; The third step is to delete the content to form one's own understanding.
6. If you want to install the ghost directly with the packaged ghost, you can download the ghost version. What you download may be a clean installation. This kind of installation system needs to be slower. After that, you have to install various applications and drivers that you don't have, but it's more stable. I prefer to use the clean version. The driver package of ghost is too large, and the drivers are all available, but the driver you find is not necessarily the most perfect, let alone the latest, All kinds of software will have to be upgraded after installation

As of November 30, 2018, convergence Holdings (and Shanghai convergence Investment Co., Ltd.) and its group president Yu Lingxiong have not been identified as MLM. People can judge whether it is MLM according to Article 7 of the regulations on the prohibition of MLM. However, it should be noted that there have been many cases of publishing blockchain by posing as Yu Lingxiong. Yu Lingxiong stated that he had only published CGK in wanshare exchange, and he would not issue a second blockchain in this lifetime
in July 2018, in view of the frequent block chain project financing activities that falsely use "Yu Lingxiong" in the market, POV chummit (Chinese Name: Yu Lingxiong, Cambodian Chinese), chairman of China Cambodia business association, solemnly declared to the outside world that Yu Lingxiong only issued the Wanbo chain (CGK) in wanshare exchange, and will not issue the second chain in this lifetime
in such an era of national financial management, with the popularity of digital money market in the era of blockchain, the undercurrent of the instry is surging quietly: there are "investment", "original stock" and "private placement price" everywhere... One wave is not flat, and another wave of "cutting leek" behavior is becoming more and more intense
However, it is undeniable that there are a large number of infringements on various digital currency investment and financing projects under the name of "Yu Lingxiong" in the marketalthough Yu Lingxiong and his platform have made many announcements and statements, many projects with ulterior motives continue to use the name of "Yu Lingxiong" to endorse their projects, which also leads to many unknown "leeks" constantly falling into the pit and suffering losses
in addition to seriously damaging Yu Lingxiong's personal reputation, it also seriously endangers the interests of the majority of investors and repeatedly discredits the investment environment of the blockchain instry
In view of this, Yu Lingxiong's "only" statement at this time is his hatred of "seizing money under his banner", and also his social responsibility to protect investors. He hoped that with such a deafening cry, Xiao users of "chain circle" and "coin circle" must enhance their risk awareness, carefully choose investment channels, and the whole people will jointly supervise the "anti-counterfeiting" to promote the healthy and sustainable development of the instry According to Article 7 of the regulations on the prohibition of pyramid selling, the following acts belong to pyramid selling:(1) organizers or business operators require other personnel developed by the developed personnel to join in through developing personnel, and the developed personnel shall be calculated and paid remuneration (including material rewards and other economic benefits, the same below) based on the number of personnel developed directly or indirectly, Seeking illegal interests
(2) the organizer or business operator, through the development personnel, requires the personnel to be developed to pay fees or pay fees in disguised form by way of subscribing for commodities, so as to obtain the qualification of joining or developing other personnel to join and seek illegal interests (3) the organizers or business operators, through the development personnel, require the development personnel to develop other personnel to join, form the relationship between the upper and lower line, and calculate and pay the online remuneration based on the sales performance of the lower line, so as to seek illegal intereststhe figure below shows Yu Lingxiong, director of convergence Holdings:
